Speakers upgrade
I just bought the GLC300 Coupe. I didnt like the sound system, not the stock nor the Burmeister too.
Did someone the speakers upgrade? im a live concert music fan (as Yanni, Dream theatre, Spyro gyra etc...).
The bass and high are enough, the mid is horrible, please any advices for mid drivers?
Thank you.

It was also recommended to use speakers for a few months to bed them in so they freed up and adjusted to car and your music.
You might find they are ‘warmer’ and the mids are improved ?




Try searching this forum under GLC speakers - you will get lots to review from various models, E, C and other classes too.
There is a German car audio company - Fischer - that under their Match and Helix line - allow you to piggy back a adapter cable into the head unit output - which in turn get's processed by their DSP to drive their amp... they have one small "micro - amp" that works pretty slick - real pro-struff.
You can cruise the W205 forum - where there is more discussion - you would go DSP/Amp - add crossovers in the front doors - use the crossover to *** front tweeters in the mirror triangles - your choice to add a sub-in the-truck.
Good hunting.
The "good" news - you can pull that stuff and move it forward to your next one when you want..

Again - the factory head unit is configured/equalized for the stock speakers only - it's the head unit equalization + lowest head unit power that "hold you back"..

The MB tweeter has a small cap/hi-pass wired into the tweeter connections.
The point is - the stock head unit is equalized/profiled to match the factory speaker system - and the Match/Helix stuff can open up a new door - they have a "VW" 4-channel DSP/amp PP41DSP that you can get a MB adapter cable - and a micro 5-channel M5DSP written up in the W205 forum.
Now Helix also has a self-contained 5-channel amp w/trunk subwoofer 000051419b that could be real/real trick
Keep the beat !
1. Can I simply add y splitter and add the factory tweeter?
2. Will I damage anything by doing this?
3. Will the sound suffer due to impedance change? As in, will I get worse sound?
Really just want to fill the higher frequencies for a fuller sound with more clarity. I don't like boomy bass and don't play loud in the car. That's what home HiFi is for imo.

Here are the items I think I need
If it was me in your shoes .. reach out to Fischer/Match US - good tech guy there - to get specifics on the correct cables to add their "4-Channel VW Amp/DSP" which can be had for like $200 .. this is the type of direction you need to start in to get somewhere really..

It looks good deal. Just need to get two extra cable PP-ISO 1 and PP-AC 13a, correct?
May I know if this 4 chanel DSP works for 4(Mid) + 2(tweeter) + 1(Sub)?
Thanks.
The reason I suggest "some" consider the 4-channel amp expansion on non-Burmester - is to open the system up to fresh DSP profiles..
